chromatographically‐stable secondary allyl boronates featuring a 1,1,2,2‐tetraethyl‐1,2‐ethanediol fragment (Epin) were obtained by kinetic resolution of their racemic mixtures. The Epin group at boron considerably improved stability of allyl boronates allowing them to be readily isolated by chromatography on silica. The resolved reagents were applied in stereoselective synthesis of homoallylic amines with an internal

The present invention provides macrocyclic compounds useful as therapeutic agents. More particularly, these compounds are useful as anti-infective, anti-proliferative, anti-inflammatory, and prokinetic agents.
Reductive amination, a convenient way to convert carbonyl compounds into corresponding amines, gains increasing attention in the amine production. In this work, we propose a continuous reductive amination process in a micropacked bed reactor using nickel catalysts. The reductive amination of benzaldehyde is chosen as the model reaction to elucidate the effects of catalyst/support, solvent, temperature
